School of Physics and Astronomy Professor Terry Jones will deliver a lecture entitled, "Who Says Pluto is not a Planet?!" at 4:00 p.m. on Thursday, September 14th in Nolte Room 125.

In August, the International Astronomical Union's General Assembly adopted a new definition of "planet" that excludes Pluto, leaving our solar system with only eight planets. Why demote Pluto? Just what makes a planet? Professor Terry Jones will untangle the planetary politics of the IAU's decision. The lecture is sponsored by the Institute for Advanced Study. The lecture is free and open to the public.
